Equipment introduction
Pre-screen Extruder is a key piece of equipment in the brick and tile production line, primarily used for raw material pre-processing and primary forming. Positioned before the vacuum extruder, it is referred to as a "pre-screen" device. This equipment screens and preliminarily compresses the raw material through a mesh plate, preparing it for subsequent vacuum extrusion molding.
This equipment is capable of mixing and extruding raw materials, thus improving its density and plasticity. The screen plate at outlet helps to filter the impurities such as grass roots and bark from the soil, in order to low the blockage accidents and save the production cost. The equipment is especially suitable for high-quality thin-wall production. The screen plate is controlled by a hydraulic system, supporting the plate replacement or changing without stopping the machine.

Functions:
1. Raw Material Pre-processing: Performs preliminary extrusion and homogenization of mixed raw materials to improve uniformity.
2. Impurity Filtration: Filters out large impurities and unbroken hard lumps through the mesh plate.
3. Enhanced Vacuum Extrusion Efficiency: Pre-compresses the material, reducing the workload on the vacuum extruder.
4. Improved Product Quality: Ensures more uniform material, minimizing defects in finished bricks.
5. Downstream Equipment Protection: Prevents large hard objects from entering the vacuum extruder and causing damage.
Structural Features:
1. Mesh Plate System: The core component, made of high-strength wear-resistant steel, with adjustable apertures based on product requirements.
2. Extrusion Screw: Utilizes a variable-diameter and variable-pitch design to gradually increase extrusion pressure.
3. Drive System: Equipped with a high-power motor and gear reducer to provide stable torque output.
4. Casing Design: Heavy-duty and robust construction, lined with wear-resistant materials to extend service life.
Technical Features:
1. High Processing Capacity: Capable of 30-100 tons/hour (depending on model specifications)
2. Adjustable Pressure: Extrusion pressure controlled by regulating mesh aperture and screw rotation speed
3. Wear-Resistant Design: Critical components made with special alloys or wear-resistant coatings
4. Automated Control: Can integrate with full-line automation systems for intelligent adjustment
